Description
ESRF machine modeling based on beam orbit measurements will be reviewed. Beta beating, coupling and vertical dispersion are corrected from this model. The minimization of the coupling resonance driving terms (RDT) allowed to reduce vertical emittance to record low values for the ESRF. Vertical dispersion then becomes a key parameter for any further reduction of vertical emittance: Its links to closed orbit errors and chromaticity will be discussed.
